I'm not sure I really dig the level of condescension here...I said pretty clearly in my earlier post that I understand there's a non-zero probability of contamination due to including an extra step (in this case, rinsing with clean--pre-boiled--water in a closed container), but that I was concerned about off-flavors. In my mind that's trading off between one risk, contamination, and another, iodine in my beer. That doesn't seem outrageous to me.
There are lots of things that we do in the brewing process that increase the risk of contamination--e.g., every time we open the fermenter to take a gravity reading, there is some chance that something bad will get into the beer. We still do it, because the value of knowing where your fermentation is at offsets the risk of contamination. Why is it that my rinsing should be a target for ridicule, but not some of the other practices we follow?
At the end of the day, we make tradeoffs between different risks--contamination, sub-optimal fermentation, off-flavors, etc--with the goal of making the best beer possible. Just because I see that particular choice a little differently than you do doesn't make me stupid, which is what I felt your post implied.
